) is an
electronic device for reading printed barcodes.
Like a flatbed scanner, it consists of a light
source, a lens and a light sensor translating
optical impulses into electrical ones.

The use of special input devices to analyze some
physical parameter assumed to be unique to an
individual, in order to confirm their identity as
part of an authentication procedure.

Types of Biometric Devices:

Fingerprint Scanning

Iris Recognition

Voice Recognition

KVM stands for "Keyboard, Video, Mouse." A
KVM switch connects one keyboard, one
mouse and one video display to multiple
computers. This allows users to control
multiple computers with only a single set of
input and output devices.
